Fedora 31: Docker Fix

I’ve updated my laptop to Fedora 31 over the Christmas holidays. Pretty much everything works as it did before. Except for Docker, which suddenly fails to start the service.

A quick Google search pointed to the discussion in this bug report, where I found the solution that worked for me:

  1. Edit /etc/sysconfig/grub
  2. Append systemd.unified_cgroup_hierarchy=0 to the GRUB_CMDLINE_LINUX variable
  3. Run “grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
  4. Reboot

Once the machine came back up gambling bitcoin, docker service was running normally.

termtosvg – record terminal sessions as SVG animations

termtosvg (GitHub repo) is a handy little tool that makes recording animated sessions in the terminal as simple as humanly possible. Instead of generating heavy graphics or video animations, this tool creates SVG files, which are a lot smaller and easier. There is also a selection of themes to choose from.

Th resulting SVG files can be used as quick demos and guides in READMEs on GitHub, or as tutorials for your application’s website.

Lazydocker is a simple terminal UI for easier management of Docker. This is particularly useful for new Docker users, but can as well save plenty of keystrokes to the seasoned administrators.
